# IP Listed on SORBS Watch

> IP Listed on SORBS Watch is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Monitors whether an IP address is listed on SORBS (Spam and Open Relay Blocking System) and alerts you when that status changes between calls.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ip-listed-on-sorbs-watch-f790514a
```

Example prompt: Keep an eye on whether 198.51.100.42 is listed on SORBS and let me know if its blacklist status has changed since the last time you checked.

## When to prefer this

Use this endpoint when you need change-aware blacklist monitoring specifically for SORBS, rather than a one-shot lookup. It is ideal for scheduled polling workflows where you want to detect transitions (listed → unlisted or vice versa) without managing your own state. Choose it over a plain SORBS lookup when you need the 'changed' signal and diff of before/after values built into the response.

## Known failure modes

- Invalid or malformed IP address returns an error
- IP not previously checked returns no change comparison (first-run baseline only)
- SORBS DNS lookup timeout or upstream unavailability may cause delayed or failed response
- Checks older than 90 days have their history purged, resetting the change baseline

## How this service works

Change watch for ip listed on sorbs: runs the check, compares it with the result from your previous call for the same ip (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current SORBS listing status for the IP, a boolean 'changed' flag indicating whether the result differs from the previous call (stored up to 90 days), the specific fields that changed with before/after values, and a timestamp of when the IP was last seen in this state.
